Spin Wave Generation via Localized Spin-Orbit Torque in an Antiferromagnet-Topological Insulator Heterostructure
Xinyi Xu, Yuriy G. Semenov, Ki Wook Kim
The spin-orbit torque induced by a topological insulator (TI) is theoretically examined for spin wave generation in a neighboring antiferromagnetic thin film. The investigation is…
Nanoscale ballistic diodes made of polar materials for amplification and generation of radiation in 10 THz-range
V. A. Kochelap, V. V. Korotyeyev, Yu. M. Lyashchuk +1
We investigate ultra-high frequency electrical properties of nanoscale -- diodes made of polar semiconductors. The calculations show that the coupling between optical…
Electrical generation and propagation of spin waves in antiferromagnetic thin films
Xinyi Xu, Yuriy G. Semenov, Ki Wook Kim
Electrical generation of THz spin waves is theoretically explored in an antiferromangetic nanostrip via the current-induced spin-orbit torque. The analysis based on micromagnetic s…
Controllable dispersion of domain wall movement in antiferromagnetic thin films at finite temperatures
Yuriy G. Semenov, Xinyi Xu, Ki Wook Kim
The dynamics of a 90 domain wall in an antiferromagnetic nanostrip driven by the current-induced spin-orbital torque are theoretically examined in the presence of random…
Diamond/c-BN HEMTs for power applications: A theoretical feasibility analysis
Namita Narendra, Jagdish Narayan, Ki Wook Kim
Diamond is a promising material for high-power electronic applications in both the dc and rf domains. However, the predicted advantages are yet to be realized for a number of techn…
Thermal fluctuations in antiferromagnetic nanostructures
Yuriy G. Semenov, Xiniy Xu, Ki Wook Kim
A theoretical model is developed that can accurately analyze the effects of thermal fluctuations in antiferromagnetic (AFM) nano-particles. The approach is based on Fourier series…
